For UCM-Holland from Sassenheim in the Netherlands, we have been able to repair a leaking boom cylinder in Nouakchott (Mauritania). The Krupp 70 GMT boom was disassembled on site with the help of a crane from the local port. The cylinder has been repaired with a seal-kit which was brought along by our engineer. After the repair, the boom has been rebuilt and the load moment limiter was re-calibrated.
